Frontiers article: The power of exact conditions in electronic structure theory, Rodney J. Bartlett, Duminda S. Ranasinghe,Chemical Physics Letters 669 (2017) 54–70

Published: Dec 9th, 2016

Once electron correlation is included in an effective one-particle operator, one has a correlated orbital theory (COT). One such theory is Kohn-Sham density functional theory (KS-DFT), but there are others.… Read More

FRONTIERS ARTICLE: Towards an exact correlated orbital theory for electrons,Rodney J. Bartlett, Chemical Physics Letters, 484, (2009) 1–9

Published: Oct 28th, 2009

The formal and computational attraction of effective one-particle theories like Hartree–Fock and density functional theory raise the question of how far such approaches can be taken to offer exact results… Read More

Many-Body Methods in Chemistry and Physics: MBPT and Coupled-Cluster Theory (Cambridge Molecular Science) 1st Edition

Published: Aug 31st, 2009

Molecular and atomic interactions are explored using many-body quantum mechanical theory. This book is the first unified treatment describing the popular many-body-perturbation theory (MBPT) and coupled-cluster (CC) quantum mechanical theory.… Read More
